Need help on figuring the checkPhone, checkEmail, and checkPassword!

OK, dudes. I figured out most of my code here and yes, I've tried it. However, I'm confused (as the title above mentions) on what I should do to get them working. Here are a couple of my theories that I have and my code is below:

checkEmail: I know it must use the "@" somewhere, so perhaps something that uses startsWith.
checkPhone: This method should test that the user has entered the first 3 digits of the phone as 972 or 214. If the first 3 digits of phone number are 972 or 214, then the phone label foreground should be set to black. If the first 3 digits of the phone are NOT 972 and NOT 214, then the phone label foreground should be set to red, so I'm assuming using substring, but I dunno.
checkPassword: Have 2 boxes for primary and verification, so...to be honest, I have no idea how I should check the text in the password textfield(primary) vs. the text in the retype password textfield(verification)...


Any info is truly appreciated.
